Anaheim, CA (Sports Network) - Anaheim Angels third baseman Troy Glaus was placed on the 60-day disabled list Tuesday, one day after it was learned he will need shoulder surgery.

Glaus, the American League leader with 11 home runs entering Tuesday's action, will have a procedure to repair fraying of the right labrum and rotator cuff. He is expected to be sidelined for at least two months and could miss the rest of the season.

The roster move is retroactive to May 12.

Last year, Glaus played in just 91 games because of a shoulder injury that ended his season in July. He did not have surgery during the off-season.

The 27-year-old slugger had been relegated to designated hitter duties earlier this month because of the shoulder problem. He then injured his right knee during a May 11 game against the New York Yankees and was sent back to California to have both his knee and shoulder examined.

Tests revealed a sprained knee ligament and a strained right shoulder. Surgery was then recommended for the shoulder.

Glaus was off to a terrific start with 28 runs batted in and a .296 batting average in just 29 games. He also has an eight-game hitting streak and leads the AL in slugging percentage at .694.

The MVP of the 2002 World Series, Glaus has 175 career homers and 501 RBI in 798 games. His home run total ranks fourth on the Angels' all-time list.

The Angels filled Glaus' roster spot by recalling outfielder Adam Riggs from Triple-A Salt Lake. He was hitting .320 with nine home runs and 21 RBI in 36 games with Salt Lake.

The 31-year-old Riggs appeared in 24 games with the Angels last season and hit .246 with three homers and five RBI. He has a career .222 average with three home runs and seven RBI in 45 major league games with Los Angeles, San Diego and Anaheim.
